The aircraft manufacturers Boeing brought back 8 of its 787 jets earlier this week after finding an issue that undermined the structural integrity of the aircraft.

Boeing confirmed that they had identified two distinct issues in the fuselage sections of the jets. The issue compromised the composite carbon fiber structure.

United Airlines, Singapore Airlines, and Air Canada were the companies affected due to the sudden grounding of the aircraft.

Officials from Singapore Airlines said that they were aware that one of their 787-10 was affected by technical issues.

“The aircraft is not in service and we will work closely with Boeing on a solution,” a Singapore Airlines spokesperson said
